Ordering the small parts with the seal kit saves the second delivery that most rebuilds otherwise need. The piston nut carries the whole shim stack and is torqued to a specification. Öhlins gives every washer and spacer its own part number because its length or thickness is part of the internal geometry.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Service parts are supplied per piece unless the description says otherwise. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21855-01. The thread is M10. Öhlins gives every washer and spacer its own part number because its length or thickness is part of the internal geometry. Sealing washers are consumables — they take their shape on first assembly and do not seal twice.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 21855-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M10\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53652888781066,"sku":"21855-01","price":14.63,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21855-01_793228e9-7ba3-4102-a775-58a309c70181.png?v=1788880347","url":"https:\/\/inter-pace.com\/en-ca\/products\/ohlins-flange-lock-nut-m10-21855-01","provider":"Inter-Pace","version":"1.0","type":"link"}
